We produce these materials from natural deposits such as granite, limestone and trap rock. Our quarrying process typically begins with drilling and blasting the rock into smaller pieces. Next, the material goes through various stages of crushing and screening to produce the sizes and specifications desired by our customers.
Construction aggregates form the underpinnings of our cities, towns and transportation networks. Thousands of years ago, civilizations built entire cities with stone, sand and gravel, and many of these ancient structures exist today.

Aggregates are truly foundational. They make up 94% of asphalt pavement and 80% of concrete. They are a vital component of our homes, from the concrete in the basement to the shingles on the roof. They are the bedrock of our infrastructure the roads, airports and waterworks that fuel our lifestyle and economy.
Aggregates is a general term for rocks and minerals used in a variety of industries for a range of purposes. Aggregate is classified by particle size and consistency. There are two basic types: sand and gravel (sometimes called natural stone)and crushed stone. More recently a third type of aggregate has emerged: recycled concrete aggregate, which is produced by crushing concrete reclaimed from demolished highways, buildings and other structures.
